H EATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 669,796, dated March 12, 1901.

Application filed November 21, 1900. Serial No.' 37.202. (No model.)

To all whom t may concern/.-

Be it known that I, SAMUEL WILDs JACK- SON, a citizen of the United States, and a resident of Selma, in the county of Fresno and State of California, have invented a new andY Improved Heating-Stove, of which the following is a full, clear, and exact description.

The objects of my invention are to provide novel details of construction for a stove which 1o adapt the stove for more efficient radiation of heat than is usually afforded in such heating devices, to economize in the consumption of fuel, and to afford simple novel means for controlling the draft in the stove, so as to render such draft circuitous or direct, as may be desired.

The invention consists in the novel construction and combination of parts, as is hereinafter described,and defined in the appended zo claims.

Reference is to be had to the accompanying,r drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

` Figure 1 is a sectional side elevation of the improved stove on the line 1 1 in Fig. 2, and Fig. 2 is a sectional plan View on the line 2 2 in Fig. 1.

The improved heating-stove, as shown in 3o the drawings, comprises a casing 10, consisting of four side Walls erected upon a bottom plate 11 in rectangular form; but it is to be understood that the outer Wall of the stove may be polygonal, oval, or circular, if preferred. The bottom plate l1 is sustained by four legs 12, and upon the side walls 10 a top plate 13 is imposed. Thetop plate and side Walls of the stove may be stably secured upon the bottom plate by any suitable means.

4o A grate 14 is supported Within the body or casing of the stove at a proper distance above the bottom plate 11 by ledges or brackets a, thus providing an ash-pitA below said grate. Above the grate 14 a tire-chamber B is formed,

Which is restricted in height by the introduction of a compartment O Within the walls 10 of the stove. As shown, the compartment O consists of a four-Walled structure, the sides 15 of which are secured upon a preferably 5o dished or concave bottom plate 16. The compartment O when constructed as shown in the drawings is held suspended from the top plate 13 by long bolts b, that engage ears c,

`formed on the bottom plate 1 6; but it is evident other means may be provided for such a purpose.

Bracket-plates d are" secured on the lower side of the top plate 13, having depending members that bear upon the outer sides' of the upright Walls 15 and serve to keep the 6o compartment O in position, wit-h its side Walls parallel with the walls 10 of the body or casing of the stove. The upper edges of the side Walls 15 are spaced suciently from the top plate 13 to produce passages between these 65 parts for the free flow of gaseous currents resulting from combustion of fuel in the irechamber B.

Within the compartment O, that is preferably termed a combustion-chamber, an- 7o other combustion-chamber D is formed by four depending walls 17, that hang from the lower side of the top plate 13 by their upper edges, which are attached to the top plate by screws or like means. The supplementary combustion-chamber D is open at the bottom, and at the lower'edges of its component Walls 17 is so spaced from the concave bottom Wall or plate 16 of the chamber O as to aiord a passage for the gaseous products of 8o combustion that have entered the compartment O. A draft-hole is formed in the top plate 13 at asnitable point for escape of smoke from the chamber D, said orifice having an encircling collar-flange f around its edge, whereon a draft-pipe 18 is to be placed when the stove is set up for service.

Near the pipe 18 an aperture is formed in the top plate 13, which is covered by a removable lid 19, and said aperture being pref- 9o erably circular affords means for the direct application of heat to the bottom of a vessel that may be hung in the aperture in the usual manner. Below` the lid 19 a stand-pipe 2O is positioned, which at its lower end is seated upon the concave lire-box Wall 16 and may project into an orilice therein, thus producing a draft-Hue, which is upright and extends from the tire-chamber B to a point near the top plate 18. The stand-pipe or lue 20 is 10o preferably furnished with a door e at its front, and a grating g protects the lower end or opening of the stand-pipe leading into the fire-chamber B.

The grating g and slots formed therethrough may be covered on the lower side by a Hat slidable gate ordamper 71that is adapted for adjustment from the exterior of the stove by a rod z', that extends from said gate outwardly through a perforation in one wall 10 of the stove-body. At the front of the stove casing or body a door 10L is hung to cover an opening in the front wall l0, and in said door lthe usual draft-register m may be placed to admit air and control the influx of the samel into the ash-pit A, and thence into the lirechamber B through the grate 14. The bottom plate 11 may be forwardly extended to form a hearth 10b, or said hearth may be separately formed and be secured inl place by any preferred means.

In the front walls of the combustion-chambers C and D apertures are formed that are respectively closed by'the doors n 0, whereby free access is afforded to said chambers for the removal of soot and ashes that may accumulate therein.

In starting a fire upon the grate 14 it will be of advantage to open a direct passage to the draft-pipe 18 through the stand-pipe or line 20, which can be readily effected by drawing the dam per or gate h from over the grating g, when the course of the products of combustion will be up through the Hue 20, and thence into the pipe 18. After the fire is burning freely the damper h may be slid to close the lower end of the iiue 20, which will cause the products of combustion to pass outwardly and upwardly between the casingwalls 10 and side walls 15 of the combustion-chamber C. When the gaseous matter reaches the upper edges of the side walls 15, it passes over them, and thence downwardly between said walls and the side walls 17 of the combustion-chamber D and the parallel side walls 15 of the other combustion'chamber C until the lower edges of the walls 17 are passed, when the draft of the pipe 18 will cause an upward flow of the gaseous products of combustion into and through the combustion-chamber D.

It will be seen that the flow of the partlyconsumed and highly-heated gaseous matter evolved by the burning of fuel in the firechamber B through the combustion-chambers C D, as stated, will perfect the combustion before the draft-pipe 18 is reached and the hot currents will impart a large proportion of contained heat to the walls 10 and the walls of the combustion-chamber, as well as to the top plate 13, from which theheat will be radiated into the apartment in which the stove is located.

It is evident that as the heat produced from combustion of fuel in the fire-chamber B is by the improved construction of the stove in a large degree saved for useful effect a less amount of fuel will be needed for the heating of a room than would be required if an ordinary direct draft were used.

' Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a heating-stove, the combination with a body or casing, a grate therein, and a door at the front of the casing, of a combustionchamber hung from the top plate of the stove within the casing, an inner supplementary combustion-chamber hung from the top plate of the stove and spaced from the other combustion-chamber, a stand-pipe extending up from the bottom wall of the outer combustion chamber into the inner combustionchamber,a grate at the lower end of the standpipe,and means to control draft therethrough.

2. In a heating-stove, the combination with a body or casing, a grate therein, and a coinbustion-chamber hung from the top plate of the stove and spaced therefrom and also spaced from the sides of the casing,of astandpipe tappingthe lower wall of said combustionchamber, a slidable damper adapted rto close the lower end of the stand-pipe, a supplementary combustion-chamber hung from the top wall of the stove within the other combustionchamber and spaced therefrom, a draft-pipe tapping the supplementary combustionchamber, and doors in the front wall of the body or casing, in the front wallof the outer combustion-chamber, and in the front wall of the inner combustion-chamber.

3. The herein-described heating-stove having a irechamber, two concentric combustion-chambers hung above said fire-chamber, one within and spaced from the other, a draftpipe extending from the top of the inner combustion-chamber, and a damper-controlled stand-pipe projecting up into the inner combustion-chamber from the bottom wall of the outer combustion-chamber.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

SAMUEL WILDS JACKSON.
